CosaTron

06/11/2025

We are pleased to announce that the CosaTron Air Purification system has been Green Certified by the Singapore Green Building Council (SGBC).
This certification is supported by rigorous testing from a laboratory accredited by the Singapore Accreditation Council (SAC-SINGLAS), which verified CosaTron's consistent efficacy in removing key indoor air contaminants:
Carbon Dioxide (CO2)
Gaseous Contaminants (VOCs)
Submicron Particles
Critically, this performance enables compliance with the ASHRAE 62.1 Indoor Air Quality Procedure (IAQP). This provides a recognised pathway to optimise fresh air intake, leading to significant energy savings and a reduced carbon footprint for building systems.
This achievement underscores our commitment to advancing sustainable building technologies and aligns directly with the objectives of the Singapore Green Plan 2030.

Have you ever noticed the dark-colored ACMV supply grilles in Changi Airport's Terminal 1 and wondered why? While this is a clever design tactic to minimize the appearance of dust, it hints at a deeper commitment to air quality that goes far beyond what meets the eye.

This commitment is exemplified by a proven case study at Dallas/Fort Worth Airport (DFW), which showcases a system that tackles air purity at its source. By adopting CosaTron technology, DFW didn't just eliminate unpleasant odors and achieve energy savings—it also drastically reduced the accumulation of fine particles on interior surfaces. Remarkably, decades after installation, the test areas remain visibly cleaner.

These results are not merely observational; the performance of CosaTron technology has been verified by a Singapore Accreditation Council (SAC)-accredited laboratory, confirming its constant removal of:

Carbon Dioxide (CO₂)

Volatile Organic Compounds (VOCs)

Submicron Particles (

CosaTron Technology has been rigorously tested for its effectiveness in contionously removing carrbon dioxide, gaseous contaminants, and submicron particles from indoor environments. This testing was conducted by a Singapore Accreditation Council-approved laboratory, confirming the technology's credibilty. Furthermore, CosaTron has achieved UL validation for zero ozone emissions, highlighting its commitment to enviromental safety.

Will it touch down in Singapore?

Experts say China's rise in HMPV cases is “consistent with global patterns”. But how does the disease compare to COVID-19 and how can we protect ourselves?

Are our buildings equipped to address this?
Submicron contaminants ARE NOT influenced by the indoor return air current.
Only contaminants of 3µm> in size will be entrained into the return air current.
Filters are static in the AHUs and waiting for the submicron contaminants to reach them.
By accelerating the natural coagulation of the submicron contaminants, they will be entrained into the return air current to be transported to the filters.
UL 2998 is a UL listing for 0 ozone emission. It is required for air cleaning devices by ASHRAE Standard 62.1-2019, Section 5.7.1

Particle counting in Indoor Air Space provides visual confirmation on whether sub-micron particles (contaminants/aerosols) are removed from Indoor Air Space to the filters. This is INCREASED FILTRATION. Minute by minute particle count has demonstrated that CosaTron Technology WORKS

Increased Ventilation and INCREASED FILTRATION are not the only means to promote clean air as neither option controls the removal of submicron contaminants from indoor air space.

Increased Ventilation to dilute contaminants comes at a price of increased energy costs

Technology that is proven to remove sub-micron contaminants will result in INCREASED FILTRATION without the need for Increased Ventilation.

CoasTron has proven its effectiveness in removing sub-micron contaminants as shown in the particles count test at JP Morgan Singapore. In the table below, 0.3 µm & 0.5 µm sub-micron particles are drastically reduced after CosaTron Air Purification System is switched on.

We breathe from the moment we are born until the moment we die. It is a vital and constant need, not only for us but for all life on Earth. Poor air quality affects us all: it harms our health and the health of the environment, which leads to economic losses. But what does the air we breathe consist...

JP Morgan's staff at the new trading floor will benefit from the better Indoor Air Quality when they are operational from September 2021 - Because Clean Air Matters

With constant change in world environment and atmospheric CO2 concentration increasing annually, together with annual periodic transboundary haze (PM 2.5) from our neighbouring countries and ASHRAE, BCA (Building Construction Authority) & CDC (USA Centers for Disease Control and Prevention) advice to increase ventilation (more fresh air intake for dilution) and filtration, these combine pose a challenge to our buildings to balance between HVAC energy consumption and better Indoor Air Quality Control.

With a proven record of past 60 years, CosaTron patented technology is able to meet this challenge.

CosaTron's technology has been proven to remove CO2 (output of human respiratory system) and pathogenic bacterias in air-conditioned/enclosed space to the filters.

Scientists have acknowledged COVID-19 is airborne and can spread through infected human respiratory system.

CO2 particle size 0.00065 μm, COVID-19 average particle size 0.1-0.5 μm

The tables from CosaTron's experiments and test shows the reduction of CO2, pathogeniic bacteria and others.

THE MOST EMPIRICAL MEASUREMENT FOR INDOOR AIR QUALITY CONTROL IS THE REDUCTION OF CONTAMINANTS IN THE AIR BEING CLEARED
